To all whom it concern,

- .Belit knownthat I, JOHN HAeE ,a citi- Zenofthe UnitedIStates,residing at St. Louis, in the city of St. Louis, State of Missouri, haveinvented certain new and useful. Improvements in Adjustable Guides forStaying Machines, of which the following is a description, referencebeing had to. the accompanying drawing andto the figures of referencemarked thereon. i :Tl1e invention relates to new and useful improvementsin tape guides and more particularly to tape guides which are as:sociated with an attachment for cutting and directingfa stay strip to astitching mech: anism.

' It has "been a common expedient in the sewing machine art tofeedbyfmeans of a manually controlled feed finger, a staystrip. to thestitching mechanism and to out said stay strip by said manuallycontrolled means. The cutting is brought aboutby a reciprocating cutterwhich moves across the path of the stay strip and severe the; same.Considerable difficulty has been experienced in properly guiding the endof thestay j strip afterit, has been cut, to gthe presser foot fortl e.nextstaying operations 7 An object-of the: present invention is toprovide guiding devices for the stay strip which are located between thecutting mech anism and the needles of the; stitching mechanism, so as tocontrolthe stay strip until it is receivedunderthe presser footand alsot' guide said stayhstrip during the Sti ch ng thereof; I

TA furthelif bjedt of. is to provide guidesof the above" character,which guides are adjustable and which are I. readily accessible foradjustment, and which are also visibleto theoperator, so that it maybeeasily seen whether the stay strip is being properly directed to thestitching mechanism.

These and other objects will in part be obvious and will in part behereinafter more fully disclosed.

In the drawings which show by way of illustration one embodiment of theinvention- Figure 1 is a plan view of.a part of a sewing machine havingmy improved guidin devices applied thereto;

Figure 2 is a front View of the same.

i919. sash 110,525,4 I In the patent granted to Benjamin. KershnerJanuary 18,; 1916,1No. 1,169,088, there is shown and described a staycutting attachment for sewing machinesfwherein the stay strip isfedforward beneath the presserfoot'by a. manually controlled finger. Theinean's whichicontrols this feeding fin geralso' operates a cutter.Whenthe lever is depressed which controls. theffinger and cutterfthecutter is raised to: sever the stay strip N Yh en weaver: is raisedthenthe feed finger moves the; tape forwardfto the front end ofthelpresserfoot and intoen gagement withthe feed. invention is I adapted totbeused in connectionwith an attachment of the fcliaracter described insaid patentflfi, I I 1 Theimproved, means for thestay strip devised bymeronsists of guiding devices located between the cutter andthe,Stitching mechanism,which guiding devices are open to viewby theoperator, so -that it can be readily determined, whether the stay stripI is being. properly guided, ,Theselggu iding devices also insurethatthe stay; strip .;when fed a forward by I the feeding! finger shallbe guided' so: thatjthe stay strip will .be properly Centeredv relative(to, l the needles.

Said guiding. devices I are also adjustable, so I as to shift theposition of the; stay strip or aewm clatastay st p p e en wi h and alsocenter thewstrips. I

fReferring more-in detail to theldrawings,

I have shown my improved guiding device applied to. stay cuttingattachment; which includes a reciprocating cutting blade, 1, cooperatingwitli a stationary. cutting blade 2i Theattachinentis mounted on thework support'ofthe sewingmachine, ,whichis indicat aerate in thedrawings. ,The feeding mechanisrnfincludes a feed dog white; isindicated at 4 in the drawings and a stitching mecha nism having twoneedles indicated at 5 and 6,

respectively, in the drawings. The stay strip is fed forward by afeeding finger which is mounted on an arm 7 carried by a shaft 8. Saidarm is oscillated by means of a lever 9 which is manually controlled bya spring 10 which moves the lever when released by the operator. Thecutter is controlled by this lever 9. These parts of the stay cuttingattachment are all similar to those shown and described in the Kershnerpatent, and have only been illustrated more or less member 11, iscarried by an arm 13 which 7.

rests on the upper face of the Work support. The cover plate 30 fthestaying attach ment proper is formed with a recess 14 and said arm 13has a projecting member 15 which lies in said recess. Said projectingniemb'er'is formed With an'open ended slot IGJ'and a setscrew 17 passingthrough the may be moved so as to adjust the" edge guide 11in adirection at right angles to the line of {feed a or h path of travel ofthe stay strip. The edge guide 12 is carried by an arm '18 which als'ohas a proje ting member l 'extendin'g into a recess 20 in the coverplate of the stay cuttingattachment and said projecting member is formedwith an 'openlendedslot 21 similartothe slot 16;, in which is placed ascrew 22. By loosening this. screw'the" edge guideIQ may be adjusted ina direction at right angles to the'line of feed or the path of travel ofthe stay stripi flhe stay "strip is ind cated at'S 1n the drawingskfSaid-stay strip passes'through the eutting attachment across the path ofmovenrent of the cutting blade: 15 which is manually controlled by theleverfl. When. said buttin blade 'is raised" the "stay strip will besewed;- This is aeconiplished by depressirig the-lever 9. When the'lever9 is raised through the action ofthe spring 10, the feed fin er movesthe stay stripiorwardly to a pointjclosefto-the' needl s 5 and .6, Theedge 'gi1ides ilfand 12'' are located between thereci roeating cuttingblade 1 for sever:

ing thestay stri and the, needles 5 and '6';

so that when this entfedge isproject'ed for wardl'yfihythe feedingfinger,'these edge guides will control and direct the stay strip untilit reache's' oint underneath th presserfif o t of e sewing machine.Furthermore, the edge guides will control the stay strip at all times asit passes from the cutting attaehment, to 1 the needles;
